The binding energy per nucleon, for nuclei with atomic mass number `A gt 100`, decreases with `A`.
The nuclear forces are weak for heavier nuclei.

Assertion The binding energy per nucleon, for nuclei with atomic mass number A gt 100 , decreases with A . Reason The nuclear forces are weak for heavier nuclei.

Assertion (A): The binding energy per nucleon, for nuclei with mass number (A) gt 56 decreases with A. Reason (R): Nuclear force is weak in heavier nuclei.
